Lining up logos with tag lines

Often, graphics design is about details. It is difficult to pin down why something just does not look right. The answer: small little things. See the bottom of a magazine ad below. The logos on the left and right have tag lines/sub brands: above on the left, and below on the right. The graphics designer simply centred the image files, but our eyes wants to centre not the entire image, but the main text of the logo. It looks like the logo on the right is positioned too high.

If you cannot get excited by this you should not become a graphics designer...
